life history
Aquatic. Described in detail by Welch (1916) and Munroe (1972). The moths come to light.

Of no concern.

diet info
The larvae feed on waterlilies according to Munroe (1972), and Welch (1916 and 1924), however, the Alberta collections by Bird are from areas where waterlilies do not occur. It, therefore, appears, as the common name suggests, that other aquatic plants are also used as food sources.

A North American species that ranges from Nova Scotia to western Ontario and south to Michigan, Wisconsin and Florida (Munroe 1972). Not reported from Alberta by Bowman (1951). Reported from Saskatchewan and the Lac La Biche area of Alberta by Pohl et al (2004). Collected in Alberta in the Winfield and Buffalo Lake areas by Bird.
